Answer:

164moles

Step-by-step explanation:

Given parameters:

Number of molecules of CO₂ = 9.86 x 10²⁵molecules

Unknown:

Number of moles = ?

Solution:

To solve this problem, a mole of any substance contains the Avogadro's number of particles.

In that;

6.02 x 10²³ molecules makes up 1 mole of a substance

9.86 x 10²⁵molecules contains
(9.86 x 10^(25) )/(6.02 x 10^(23) ) = 1.64 x 10²moles

The number of moles is 164moles
